For psychological purposes the most important differences in conation are those in virtue of which the object is revealed as sensed or perceived or imaged or remembered or thought.

But though cognition is not an element of mental action, nor even in any real sense of the word an aspect of it, the distinction of cognition and conation has if properly defined a definite value.

The perceptive act is a reaction of the mind upon the object of which it is the perception.

Mental life is indeed practical through and through. It begins in practice and it ends in practice.

You can mark in desire the rising of the tide, as the appetite more and more invades the personality, appealing, as it does, not merely to the sensory side of the self, but to its ideal components as well.

Both expectations and memories are more than mere images founded on previous experience.

Psychology is the science of the act of experiencing, and deals with the whole system of such acts as they make up mental life.
